Skeletal and cardiac muscles are striated, smooth and cardiac muscles are involuntary, cardiac muscle is only found in the heart, and skeletal muscle is multi-nucleic. Muscle fibers are also known as muscle cells and micro-filaments are responsible for muscle contraction. Our muscles are responsible for producing movement, maintaining posture, stabilizing joints, and generating heat. There are also 4 characteristics of muscle: excitability, contractability, extensibility, and elasticity. They are correspondingly the ability to respond to stimulus, the ability to shorten forcibly, the ability to stretch forcibly, and the ability to recoil after being stretched. Of the three connective tissue wrappings, endomysium surrounds single muscle fibers,perimysium surrounds a fascicle, and epimysium covers the entire skeletal muscle.]]> 2021-02-08 13:30:52 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176771474 https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176772255 Muscles are divided into 3 types which are cardiac, smooth, and skeletal muscle. smooth and cardiac are involuntary while skeletal is voluntary. Also cardiac and skeletal muscle have striations while smooth doesn't. Terms in muscle is muscle fiber which means muscle cell, myo and mys which both means muscle, and sarco which means flesh.The 4 characteristics of muscles are excitability, contractility, extensibility, and elasticity. The four functions of muscles is to produce movement, help maintain posture, stabilizes the joints, and generates heats.]]> 2021-02-08 13:31:00 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176772255 https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176772781 With the many functions of muscles, the responsibilities need to be done by several different types: skeletal, cardiac, and smooth muscles. Smooth muscles lack striations, have spindle-shaped cells, are involuntary, and contain a single nucleus. Cardiac muscles area only found in the heart, contain striations, are involuntary as well, and keeps a steady pace. Skeletal muscles are the longest muscle cells, contain striations - visible stripes, are voluntary, and tire easily. 
Muscles do contain their own characteristics and functions though; those characteristics being irritability, contractility, extensibility, and elasticity. The functions consist of movement, maintaining posture, stabilizing joints, and generation of heat. Along with those similarities, they also share some terminology: the prefix "myo" which refers to muscle, the prefix "mys" which refers to muscle as well, and the prefix "sarco" which refers to flesh. Each are used in their own terms: Endomysium - Around single muscle fibers, perimysium - Around a fascicle of fibers, and epimysium - Covers the entire skeletal muscle. Do note that each contain muscle cells (muscle fibers) that are elongated, and microfilaments which are responsible for contractions.]]> 2021-02-08 13:31:05 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176772781 1188319 https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176774357 Cardiac and smooth muscle is involuntary muscle, and skeletal muscle is voluntary. Muscles are contactable, extensible, elastic, and irritable. Muscle cells are also muscle fiber. The prefix myo means muscle, the prefix mys means muscle, and the prefix sarco means flesh. Micro filaments assist in cell movement. The insertion is the movable attachment for the muscle, The origin remains relatively fixed during muscle contraction. ]]> 2021-02-08 13:31:26 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176774357 https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176774876 There are three types of muscles which are cardiac, smooth, and skeletal. The four characteristics of muscles are excitability, contractility, extensibility, and elasticity. The functions of muscles are maintains posture, produce movement, stabilize joints, and generate heat. With the cardiac muscle, it has striations, involuntary, and has a single nucleus. With the smooth muscle, it has no striations, spindle-shaped cells, and involuntary. With the skeletal muscle, it is voluntary, has the longest muscle cells, and it contract rapidly. ]]> 2021-02-08 13:31:33 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176774876 https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176778561 there are 3 different types muscles; cardiac, smooth, and skeletal. the muscle tissue contains something called muscle fibers; they help to control the physical force within the body, also there are microfilaments, aka actin filaments, they assist with cell movement, mys protects muscles from friction against other muscles and bones, myo facilitate function in muscles, and the sarco acts like a barrier b/w the extracellular and intracellular compartments. muscles have some characteristics; excitability, contractibility, extensibility, and elasticity. the endomysium is a wispy layer of areolar connective tissue, perimysium is the sheath of connective tissue, and epimysium is a sheath of fibrous elastic tissue. ]]> 2021-02-08 13:32:18 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176778561 https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176779829 There are 3 different muscle types: Cardiac, Skeletal, and Smooth. Cardiac and smooth are involuntary, while skeletal is under conscious control. There are also 4 characteristics of muscles: Excitability, contractility, extensibility, and elasticity. Excitability is the response the muscle gives to an action. Contractility is to flex/contract. Extensibility is how much the muscle can be stretched. Elasticity is to then return to the muscle's original length.]]> 2021-02-08 13:32:34 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176779829 https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176785372 There are three types of muscles: Smooth, cardiac, and skeletal. Skeletal is the only voluntary muscle, while cardiac is involuntary it moves at a steady pace, as opposed to smooth muscles that are found in the walls of hollow organs. Despite those differences every muscle shares these characteristics: Excitability( irratability), Contractility, Extensibility, and Elasticity. Along with characteristics all muscles share terminology. For example, the prefixes myo(muscle), mys( muscle), and Sacro(flesh) can all be found in the muscle world. ]]> 2021-02-08 13:33:48 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176785372 https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176809332 cardiac, smooth and skeletal are the three types of muscle. each muscle has different characteristics.. smooth muscle has a single nucleus and is involuntary and found mainly in the walls of hollow organs. cardiac is also involuntary and is a steady pace. skeletal is voluntary. there are 4 different functions extensibility, elasticity, excitability and contractility.]]> 2021-02-08 13:38:41 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176809332 https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176814346 Smooth Muscle has no striations, spindle-shaped cells, single nucleus, and are involuntary(no conscious control). These muscles are found mainly in the walls of hollow organs and are slow, sustained and tireless. Then we have Cardiac Muscle which has striations, usually has a single nucleus, and are joined to another muscle cell at an intercalated disc. they are also fond in the heart and are involuntary. The third type is Skeletal Muscle which are the longest muscle cells, striations (visible stripes), voluntary, and can contract rapidly, but tires easily and must rest after short periods of activity.
Terminology of Muscles are Muscle Fiber, Microfilament, Mys, Myo, and Sarco. Muscle Fiber are muscle cells that are elongated. Contraction of muscles is due to the movement of Microfilament. Prefix myo refers to muscle. The prefix mys refers to muscle. lastly the prefix sarco refers to flesh.
Some Characteristics of Muscles are Excitability (irritability) which is the ability to receive and respond to a stimulus. Then we have Contractility is the ability to shorten forcibly when adequately stimulated. Extensibility is the ability to be stretched or extended and Elasticity is the ability of a muscle fiber to recoil and resume its resting length after being stretched.

To start off the four functions of muscles are maintaining posture, allowing movement, stabilizing joints and producing heat. Also the four characteristics of muscles are extensibility, contractibility, excitability and elasticity. Furthermore muscles can be broken up into 3 categories: smooth, cardiac and skeletal muscles. A similarity between cardiac and skeletal is they are striated whereas smooth is not. Among other things the muscles are separated by location, the cardiac muscles are in the heart, the smooth muscles are on the walls of hollow organs, and skeletal muscles are located between bones. Skeletal muscles are under conscious control therefore they are voluntary where as cardiac and smooth are not.]]> 2021-02-08 13:54:45 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1176892073 https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1179374090 There are three types of muscles, including cardiac, smooth, and skeletal. While Cardiac and smooth are involuntary, skeletal is always under conscious control. These muscles all share the four main characteristics for muscles. These characteristics are conductibility, excitability, elasticity, and extensibility. The muscles are used to maintain posture, produce heat, allow movement, and stabilizing joints. Muscles are a key part of our bodies. Without them we would not be able to accomplish our everyday task needed to survive. ]]> 2021-02-08 21:02:19 UTC https://padlet.com/crhodan1/bgaoymx2bvc7mffn/wish/1179374090
